On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001.  This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V-274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001).  GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274.  This presents a potential safety risk that warrants further investigation.  ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024.  GM cited the root cause as a supplier manufacturing and quality issues. GM’s  recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).

I own a 2024 Chevrolet Tahoe RST and have experienced recurring electronic/electrical problems despite multiple dealership visits. The vehicle repeatedly displays “Open Then Close” window messages for the passenger or driver window even though the windows function normally. While driving, the infotainment screen has repeatedly gone black, causing the audio/music and audible turn-signal indicator/chime to stop working. On one occasion while stopped at a red light with the vehicle running, the infotainment screen and entire instrument cluster went blank and rebooted. The Chevrolet logo remained displayed during the restart, and the audio and turn-signal chime stopped working. The dealership has been unable to duplicate the issue but has performed software updates. The problems continue. Most recently, the vehicle displayed “Service Transmission Now — Unable to Shift Soon.” The warning disappeared. The dealership then stated the 12-volt battery was low and needed replacement before accurate diagnostics could be performed. I replaced the battery, and afterward the check-engine light came on. A complete diagnostic has not yet been performed because my appointment was rescheduled. I am concerned these recurring electrical/electronic issues, transmission warning, and check-engine light may indicate an underlying safety-related defect. I am requesting that GM formally document and investigate these concerns.

Tahoe was purchased new in November 2024. Vehicle currently has around 37,000 miles and has been regularly serviced by GM dealers. On Sept. 9, 2026, was driving in moderate rain and wipers just stopped working. After stopping at a nearby gas station for about 5 minutes or so, the wipers again began working. I am currently having intermittent wiper failure. Sometimes they are really slow even on the “high” setting. Something is wrong with them and fuse was checked and is good. This creates a very dangerous situation that could cause serious injury or death if the wipers (on a new $80,000 vehicle) suddenly stop while driving in rain. This is a serious danger to public safety and GM needs to issue a recall for a fix. Research online indicates GM is aware of the issue under TSB PIE0774, but is not offering resolution to vehicle owners. As well, online research shows a class action lawsuit is pending. The NHTSA needs to take prompt action and direct GM to correct the matter for public safety.

Brake System Failure 62 MPH Top Speed Service ESC Service Brake Trailer System These warnings appeared on 04/30 and my brakes became extremely hard to use to stop my vehicle. I had my two young children in the car, I was able to go up hill and shift it into park after driving 15 minutes basically with no brakes. It was towed to Hendrick Chevrolet, where they replaced the master cylinder. On May 5th I was driving the car and the service brake assist light came on with the message. I then had it towed to Hendrick where it stayed until July 28th. The dealership stated that it was an external leak in the master cylinder. Now for the 3rd time the brakes are making a squealing noise and the service brake assist light is on again. I do not feel safe in this vehicle.

Engine locked up from crankshaft bearing failure, mega fuse blown My wife and I were driving 70mph on a highway when I lost the throttle and other power. I pulled over to the side the best I could but barely over the white line. It was a dangerous situation for us & tow trucks, the engine was locked up & the flat bed truck couldn't tow vehicle. The 2nd truck was a reaper style truck which was dangerous to setup on the side of highway. The dealership diagnosed and replaced engine to their guidelines. I requested the oil cooling lines & housing be replaced as well to avoid metal debris to enter new engine to avoid recurring engine failure. At first both requests were denied, then another dealer represntive said the oil lines would be replaced but the housing would not be. I even offered to pay for that replacement which was denied. I invested a lot into the vehicle, I was assured the original recall and engine oil change would be sufficient. I also purchased to dealer premium care package to really take care of my vehicle investment.Engine failure was around 29,000 miles. The engine failure happened on a Sunday morning, I didn't receive any loaner car or rental car until Thursday affecting my work transportation. Once the dealer rented me a car, I asked if I needed anything to pick up the car, dealer rep said no. Once at rental car place, I needed a credit card and ID, I was charged $250 for the time I had the rental car. The rental car was not close or comparable to my vehicle, which I still had to make payments while it was broken at the dealership. I really worry about my safety, reliability and travel going forward with this vehicle. I also am very concerned about the vehicle losing value due to known issues. There was no warning signs until the failure, I believe the dash message said 'please press start' or 'press start'. Overall this has been a tough and stressful situation with my expensive vehicle investment. Vehicle unavailable- 7/26-8/17

While driving, my Chevrolet Tahoe suddenly developed a severe, rhythmic bottom-end engine knock, indicating a catastrophic internal mechanical failure. I immediately took the vehicle to an authorized Chevrolet dealership on May 29, 2026, for emergency diagnosis.The dealership technicians officially diagnosed the issue as a severe lower-end engine failure. They deemed the engine unrepairable and determined that a complete long-block engine replacement is required.As of today, July 6, 2026, the vehicle has been sitting at the dealership for over 5 weeks and has yet to be fixed. The prolonged delay and sudden mechanical failure present a severe safety hazard, leaving me without a vehicle due to known GM manufacturing defects currently under NHTSA investigation. This report is being filed to document the failure of the 6.2L engine lower end, the necessity of a full long-block replacement, and the ongoing repair delay.
